    What is SFC of IVC series PLC The SFC of IVC series PLC is a programming language used by INVT IVC series PLCs. Besides standard SFC functions, the SFC of IVC series PLC can provide multiple nested LAD program blocks.
  • Page 241 Programming manual of IVC series small PLC Chapter 7 SFC tutor Table 7-1 Programming symbols Symbol name Symbol Description A initial step of SFC, numbered as Sn. The “n” must not repeat. The execution Initial step of a SFC program must start with an initial step, whose S element range is S0~S19 A normal step, numbered as Sn.
  • Page 242 Programming manual of IVC series small PLC Chapter 7 SFC tutor In a simple structured SFC program, when the step transfer conditions are met, the program will run from the current step to the next step in a linear flow. At the last step, when the transfer conditions are met, the SFC program section will exit end or transfer to the initial step.
  • Page 243 Programming manual of IVC series small PLC Chapter 7 SFC tutor 2. Selection merge The selection merge is the structure where all selection branches merge to the same step. The transfer conditions are set respectively. As shown in the preceding figure, the transfer condition in the branch of S27 is that time is up for T12, while that for the branch of S28 is that time is up for T13.
  • Page 244 Programming manual of IVC series small PLC Chapter 7 SFC tutor In the SFC, when step S22 is valid, the program may jump to step S21 to recycle S21 and S22, or jump to the initial step S0 to recycle all the steps. Which recycle will be selected is determined by a selection branch structure. While in the LAD, the two kinds of jumps are realized in row N3, where you can see the OUT coil.

  • Page 245: Relationship Between Sfc Program And Lad Program

    Programming manual of IVC series small PLC Chapter 7 SFC tutor On the other hand, their difference lies in that in a SFC program, the steps’ validity will change according to certain conditions, and only valid steps can be executed. While in a LAD main program, the whole program will be scanned and executed in each scan cycle.

  • Page 246: How To Program With Sfc

    Programming manual of IVC series small PLC Chapter 7 SFC tutor As shown in the LAD program, the S2 step starts with a STL instruction, and the following TON instruction is the internal instruction of S2. A step can be made up of multiple instructions. A SFC step is actually a relatively complete program section, almost consistent with the LAD counterpart.

  • Page 247: Points To Note In Sfc Programming

    Programming manual of IVC series small PLC Chapter 7 SFC tutor 4. Make a list of input and output points, and determine the objects of each procedure and the transfer conditions Generally, the input points are transfer conditions, while the output points are the operation objects. In addition, with the list, you can further modify the SFC.
  • Page 248 Programming manual of IVC series small PLC Chapter 7 SFC tutor As shown in the following figure, the two neighboring steps use the same timer: T2. When the S0-S20 transfer occurs, the T2 will retain its value and state, rendering the step S20 unable to perform as it is designed. The program will jump directly to S21 and S22.
  • Page 249 Programming manual of IVC series small PLC Chapter 7 SFC tutor Confusing jumps with transfers Jumps are used between different procedures or non-neighboring steps, while transfers are used between neighboring steps. It is prohibited to change an output coil into a SET instruction where a jump should be used, or change a output coil into a SET instruction where a transfer should be used.

  • Page 366 Based on the storage method of PLC in GCM, one LONG INT data can be saved in two D elements. For example: Store one LONG INT data in D3 and D4, D3 is used for storing high 16 bits, D4 is used for storing low 16 bits in INVT PLC. If master station reads LONG INT data through Modbus, the 32-bit data shall be regrouped based on the LONG INT storage principle of INVT PLC after reading the data.

Description of broadcast The slave station supports broadcast but not all the function codes. The slave station supports function codes 01, 02, 03, 05, 06, 08, 15 and 16 (decimal).
